Appendix B: Connector Pinouts

The QVGA Controller comprises a stack of three boards: a
display backplane, the QVGA Board, and the smaller QED-4-QVGA Board (aka
QED-Flash Board). Pin-outs for all I/O connectors on the QED-Flash Board or the
QVGA Board are provided here.

Warning  Do
Not Connect to System Control Signals

When connecting
to the Digital I/O Connector (H2 on the QVGA Board) with a ribbon cable, notch
out cable wires 11 through 24. Even short pieces of wire connected to some of
these lines may cause intermittent operation of the touchscreen or processor.

When connecting
to the Supplemental I/O Connector (H3 on the QED Board) with a ribbon cable,
only connect the wires you need, and do not connect to the data bus lines or system
control lines.

QED Flash Board Connectors

The pinouts of all of the connectors on the QEDFlash Board are presented below. To locate the
connectors on the board, consult Figure B1 and the white silkscreened labels on the visible side of the QEDFlash Board. The arrows in the figure point to the
locations of pin 1 on each connector.

* HC0 is generated by the PAL, HC1HC3 are generated
from PB5PB7 respectively.

You should not connect to the shaded signals.
Even a short wire connected to these lines may cause malfunction.

You
should not generally need to connect to the processor's address and data
bus. Please consult Mosaic Industries before attempting to connect to these
signals.

Processor Port E may be
used as either 8bit A/D inputs (AN07) or as digital inputs. 12AN0-7 are
12-bit A/D inputs. Vin1-8 and Vout1-8 are the 8-bit multiplying DAC inputs
and outputs.

QVGA Board Connectors

The pin-outs of all of the connectors on the QVGA Board
are presented below. To locate the connectors on the board, consult Figure B‑2
and the white silkscreened labels on the visible side of the QVGA Board.

Pins
7 and 8 (CTS1/RTS1) may optionally be connected on the board with zero ohm
shorts.

Pins
7 and 8 (CTS1/RTS1) are connected.

Notes:

Headers
H2 and H4 are connected in parallel. H4 connects to the QED Board, and H2 is
available for you to connect to.

You
should not need to connect to the shaded signals. When connecting a ribbon
cable to H2 you should notch out the wires corresponding to the shaded
signals, pins 11 through 24. Even short lengths of wire connected to these
signals may cause intermittent operation of the processor or the touchscreen.
